WATER-CLOSET.

To all whom it may concern:

.Be it known that I, ANDREW CocHRAN, a citizen of the United States, and a resident of Trenton, Mercer county, New Jersey, have invented certain Improvements in Vifater- Closets, of which the following is a specifica tion.

My invention relates to water closet bowls which are. emptied by siphonic action; andthe object of my invention is to provide an improved form of'discharge or outlet for water atthe back of the bowl whereby sufli cient force is developed at. such point in line with the ascending leg of the siphon to insure siphonic action asquickly as possible and clean the contents of the bowl.

A further object of my invention is to provide such discharge opening flush with the surface of the bowl so as to avoidall proj ectingparts susceptible of retaining foreign matter; to discharge through the same a volume of water greater than that passing through the outlets of the flushing rim; to arrange such discharge above the level of the water seal, and to continue the outlets of the flushing rim entirely around the same so as to insure the washing down and cleansing of the whole inner surface of the bowl, particularly that portion of the same directly above the discharge outlet in the rear wall of the bowl.

My invention is fully shown in the a-ccom-.

panying drawings, in which:

' struction has been such that the entrance of Figure 1, is a sectional elevation of a 'water closet bowl of the siphonic type havin the improvements forming the subject oi? my invention; Fig. 2, is a sectional erspective View of a ortion of the same; ig. 3, is a sectional p an view of: apart of the structure; Fig. 1, is a sectional elevation showing the inner surface of the bowl, and Fig. 5, is a sectional view of another form of closet with which my improvements have been combined.

Heretofore in closets of this type the conthe jet of .Water to induce siphonic action necessitated the use of a rojection or enlargement on'the interior of the closet at the rear jVfill of the same; The presence of said projection was such that any dirt which might collect on the. same could not be rinsed or flushed away owin to the factthat the pro jection prevented t e continuation of the ansuch purpose.

nular row of perforations leading from the flushing rim around the rear of the closet.

In the construction of a closet of the above described type in accordance with my invention, I eliminate the projection providing a nozzle for the jet of flushing water, (which mayor may not be used for flushing purposes,) and provide a passage havin an outlet flush with the rear wall of the owl for In addition, I continue the annular row of openings leading from the flushing rim completely around the bowl.

In the drawings herewith, 1 represents a water closet bowl having a water inlet 2 and 3 the usual rim 3 arranged to receive a certain portion of the water for flushing the bowl; such rim having outlets 4 in its under wall whereby the water entering the same may flow down against the side walls of the bowl during the flushing operation, thereby maintaining the same in a perfectly clean condition. In my improved construction, the row of perforations extends entirely around the bowl.

My improvements are applied rincipally to closets of the well-known sip onic type such as shown in Fig. 1, in which 5 reprei sents the ascending leg of the siphonic discharge, and 6 the descending leg which is rovided with the usual projecting portion 7 designed to cause the water to shoot across said descending leg, thereby creating a vacuum and pullin When the main volume of such discharge has taken place, the remammgwater will enter the bowl and form a water seal;

the height of which is determined by the inner wall of the discharge leg of the siphon.

In view of the sanitary regulations of the various cities of the country, I provide a closet having a particularl deep water seal, thereby insuring against oul odors passing from the discharge outlet, and with such volume of water it becomes desirable to insure the formation of the vacuum and the inducing of the siphonic action as quickly as possible. To this end, I provide. the rear wall. of the structure with a passage 10 communicating withthe water inlet 2 androceivin the greater quantity of the main supply of water from said inlet; such passage discharging into the bowl 1, directly opposite the ascending leg of the siphon; such the contents of the. bowl and the water ischarged therein out of the same.

' matter around thesame impossible, and the water rushing from this opening is discharged in such position as to force the conj tents of. the bowl up the ascending leg of the siphon whereby a suflicient volume under 'sufiicient head or force will be discharged into the descending leg as to close the same and create the vacuum beforereferred-to;-

thereby insuring siphonic action. The other portion of the. main supply discharges through the aperturesin the bottomnpf thi the bowl in '"theflinannercompletely rim surroundmg n I heretofore known, washmgdown the whole surface of said bowl.

' urectly abovedt and cascading over It will be notedthat'the outlet or opening 11 is above the level .of water irfiitlie,howl v forming the seal so that it can .never fieome; in-eontact with the contents of the bowl and will always be kept clean by the water-dis-, charging from it ss well as that, flowing from the openings of the flushinirimdihat portion of 'the wall immediately above said opening 11.

In Fig. 5 I have shown a form of washout elosetwith whichmy-im roved form of flushing rim construction an nozzle iscombined, the, discharge of'a large. volume of mits the use of much less water water at therear of the bowl materially assisting the cleansing of the closet.

My lmproved construction of iuflushing the same; practice showing that it can be made to operate with at least, two gallons" of water less than'that used with closets of the ordinary jet siphon type.

My improved closet may be constructed as readily as other closets'of the same general type and. is superior to them in its 0 era'tion.

I consider itbroadly new to provide means for delivering water entirel around the bowl from a flushing rim, .wit means for discharging a large su ply at one point from the surface of such owl. I also consider it broadly new to provide the opening for such large supply above the water seal and flush with the surface of the bowl, to dispose it directly opposite the ascending leg of the siphon discharge, and to so connect it with the inlct of water that the volume discharging from such passage shall be greater than I that discharging from the flushing rim'.

I claim:

a large volume of water *the contents of the bowl.

closet v pen I said bowl .havin l. A water closet bowl having a wall with a smooth inner surface free from projection, a flushing rimhaving a series of openings entirely surrounding said bowl through which water may be delivered to the inner surface of said wall, said bowl having at its rear central portion a substantially vertical passage with an outlet opening throughthe wall of the bowl above the level of water therein for delivery to said bowl in the same direction as the delivery fromthe flushing rim, and a water inlet. supplying the flushing rim and the rear passage leading to the bowl, the front wall of the latterserving to divert the incoming water whereby said passage receives directly under initial pressure suflicient to eject 2. A water closet bowl of thegsi'phont pe having a wall with .apsm'cioth inner'surfzice free from proiectioma flushing rim having a series of openings entirely-1 surrounding said bowl through which water may be delivered to the inner surface of said wall, a passage formed in the rear wall of said bowl having anoutIet openin through therwall of the [bowl above the le vel of water therein fur delivery to said bowl in the same direction as the flow from the rim, and a water inlet formed in the rear wall of said bowl for Supplying the flushing rim-and the rear passage leading to the owl, said passage receiving directly underinitial pressure a larger volume of'water than thatspassing to the flushing rim vgherebyfthe contents of the bowl may be prd ptly Iejected-andsiphonie action induced andmainta'ined.

3. The combination of a water closet bowl having-a wall with a smooth inner surface free from projection, of a flushing rim for a series of dischar en'outlets through whlch water may be de ivered to saidiinner surface ofthe bowl, said bowl having a passage at'therear for discha-r water in ,the same direction as that discharged-from the outlets of the flushing rim, and an inlet for water communicating with said flushing rim and with the passage at the rear of the bowl, the latter receiving under initial pressure a a volume of water greater than that passing through the flushmg rim, and said passage having its outlet flush with the inner surface of the wall of the bowl and opening into the latter above the water seal.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
